Abstract

The invention relates to a building bar system, in which horizontal bars (2) are located between the vertical columns (1) of the building, the horizontal bars bearing shell slabs (22), which form the intermediate floor for the building. The horizontal bar consists of the plate girder (3, 4, 5), to which a tensioned pre-raising has been provided with tension bars (6) between the plate girder (3) and the vertical column (1).

Description

Building bar system
The present invention relates to a building bar system, in which horizontal bars have been arranged between vertical columns of the building, the horizontal bars bearing shell slabs, which form the intermediate floor for the building.
The horizontal bars usually consist of steel bars, which are manufactured of a very thick steel sheet or steel sheet profiles, filled with reinforcement and fresh concrete.
The object of the invention is to produce a completely new type of a building bar system, in which the intermediate floor for the building is cast directly onto the bars bearing the shell slabs. It is characteristic of the building bar system of the invention that the horizontal bar consists of a plate girder, to which a tensioned pre-raising has been provided with tension bars located between the plate girder and the vertical column. Shell slabs are arranged onto the horizontal flanges of the plate girders of the horizontal bars, and thus a slab layer covering the whole floor is provided. After this, fresh concrete is cast around the vertical columns and the plate line so that the tension bars are covered. After the first concrete casting has hardened, we have a very strong intermediate floor structure, onto which a second concrete casting can be performed, forming the levelled floor structure for the intermediate floor. A so- called slab arrangement of continuous structure is provided, the building loads of which are about a half of the known intermediate floor solutions.
It is characteristic of one embodiment of the invention that the tension bar is from its other end attached to the grip projection in the plate girder and from the other end to the lug projection protruding from the vertical column, using a tightening wedge anchor or nut coupling.
It is characteristic of a second embodiment of the invention that the longitudinal middle section of the plate girder is bent upwards to A shape, and that the vertical columns have respective A-shaped support projections. Thus, the plate girders can easily be arranged between the vertical columns.
It is characteristic of a third embodiment of the invention that second upwards bent A profiles are arranged on both sides of the A profile and that the grip projections are located at the length of about 1/3 from the ends of the plate girder and that they are fastened between the perpendicular walls formed by the A profiles. Other embodiments of the invention are presented in the patent claims.
The invention is next described in more detail referring to the enclosed drawings in which
Figure 1 is an axonometric view of the vertical column and two plate girders,
Figure 2 presents the mechanical joint between the vertical column and the sheet profile,
Figure 3 is a top view of four vertical columns and sheet profiles and composite slab profiles,
Figure 4 is a section of Figure 3 along the line IV-IV,
Figure 5 is a section of Figure 3 along the line V-V,
Figure 6 is an end view of the sheet profile,
Figure 7 is an end view of the edge parts of the sheet profile, and
Figure 8 is an axonometric view of the intermediate floor partly cut at the point of the horizontal bar.
Between the vertical columns 1 of the building bar system for a building there are horizontal bars 2, which bear shell slabs. The slabs can be shell slabs 22, cavity slabs or composite slab profiles. The horizontal bar 2 consists of the plate girder 3, 4, 5, to which a tensioned pre-raising has been provided with the tension bar 6 or wedge anchor located between the plate girder 3 and the vertical column 1. The tension bar 6 is attached to the grip projection 7 in the plate girder 3 from its one end and from the other end to the lug projection 9 protruding from the vertical column 8, using the tightening nut coupling 8. The longitudinal middle section of the plate girder 3 is bent upwards to A shape 10, and the vertical columns have respective A- shaped support projections 11. On both sides of the A profile 10 there are second upwards bent A profiles 12. The grip projections 7 are located at the length of about 1/3 from the ends of the plate girder and attached between the perpendicular walls formed by the A profiles 10, 12. On the edge plate girders 4, 5 there is the half A profile 13 the height of the mould, which works as the mould wall in the concrete casting. In the Figures there is shown the plate girder 3, through the A profile 15 of which the concrete reinforcement 14, the shell slab 15 on the flange of the plate girder and the fresh concrete 16 cast onto it are attached. The fresh concrete 16 is cast in two parts, the first casting 17 and the second casting 18. The plate girder works as a composite slab. Between the plate girder 3 and the vertical column there is intentionally a considerable gap so that a margin extending in the longitudinal direction of the sheet profile can be provided for the thermal expansion caused by a possible fire arising below. The first concrete casting is made around the vertical columns 1, the points 17, so that very strong concrete structures can be achieved around the vertical columns and the second casting 18 is allowed to spread onto the whole layer, forming the intermediate floor and, simultaneously, the floor level.
The first concrete casting 17 onto the bar line extends about 1/3 onto the shell slabs 22, Figure 5. Thus, the tension bars 6 and the plate girders 3 are fully covered. As the concrete reinforcement 14 is still arranged through the plate girders 3, the plate girder 3 becomes a composite bar. This entirety forms about half of the structural loads. After this, the middle sections are cast and the surface of the slab arrangement is made.
